Discharging of some affluent insufficiently treated has led to the alteration of streams and to the apparition of a wide range of contaminants: organic substances, hardly degradable, nitrogen, phosphor and sulfurs compounds, microelements (copper, zinc, lead), pesticides, organic- chlorinated insecticides, detergents, etc. A feature of the river’s water is the self-cleaning capacity, due to a series of natural biochemical processes, favored by the contact air-water. The self-cleaning process is made by the action of some environment agents, of a physical, chemical and biological nature, which may simultaneously interfere or in a succession order. But when water pollutants overpass the self-cleaning process, wastewater treatment plants are required. In the present paper work it is presented the Timisoara wastewater treatment plant and it is made an analysis of self-cleaning capacity of the waste water treatment plant in 2016 and 2017. One may notice that, after the performed analysis, there is an increased efficiency of the Timisoara city waste water treatment plant by the fact that at the entrance of the waste water treatment plant, values are much above the maximum allowed value, and after the self-cleaning process, values have been much beyond under the limits allowed by the law.
